Never Doubt a Duke by Regina Scott

After spending the last ten years following her late husband on campaign, the irrepressible Jane Kimball finds herself badly in need of a position to support herself. Marriage holds no appeal; she’s not likely to find a husband like her Jimmy again. But when Miss Thorn of the Fortune Employment Agency offers her a post with the Duke of Wey, Jane feels drawn to help the lonely widower with his three daughters. He may seem a bit aloof, but Miss Thorn’s cat Fortune approved of him. Why should Jane doubt a duke?

Alaric, Duke of Wey, commands his staff, his tenants, and the halls of Parliament, managing vast holdings in England and across the seas. Why is it he cannot manage his own daughters? As an old danger rears its head, he comes to rely on Jane’s practical nature, her outspoken ways to navigate the waters of fatherhood. And when necessity dictates he take a wife, thoughts turn to an unlikely governess who might make the perfect bride.
